The Seneca people have lived in the Western part of New York State since time immemorial and consider the area their aboriginal home. After preserving two territories — or reservations — in Western New York, the Seneca people developed their own constitution and elective form of government, officially becoming the Seneca Nation of Indians in 1848.

In 2002, the Nation entered into the Nation-State Gaming Compact with New York State, which granted the Nation the exclusive right to build and operate three Class III gaming facilities in Western New York.

Seneca Gaming Corporation was chartered in August 2002 to manage the Nation’s gaming operations. Seneca Niagara Falls Gaming Corporation was also chartered at this time, and Seneca Niagara Casino opened its doors on December 31, 2002. SNFGC opened a luxury hotel, the 26-story Seneca Niagara Resort & Casino, on December 30, 2005.

Seneca Territory Gaming Corporation was chartered in August 2003 to manage the Nation’s second Class III gaming operation. On May 1, 2004, Seneca Allegany Casino officially opened for business. STGC opened the Seneca Allegany Resort & Casino on March 30, 2007.

In September 2003, Seneca Erie Gaming Corporation was chartered for the purpose of managing the Nation’s third gaming operation permitted under the Compact. In October 2005, the Nation acquired 9 acres of land in the Inner Harbor area of downtown Buffalo and designated the land as its preferred site for constructing a Class III gaming facility. On July 3, 2007, SEGC opened a temporary Seneca Buffalo Creek Casino on the nine-acre territory. It underwent two expansion projects in 2008 and 2010. In March 2012, the Seneca Nation of Indians and Seneca Gaming Corporation unveiled a re-designed $130 million Seneca Buffalo Creek Casino on the Nation’s territory in downtown Buffalo. The property celebrated an official grand opening on August 27, 2013.
